Actually, the same plugin should work. We should be able to branch inside
based on what the platform is.
In fact, looking at RcppGSL/R/inline.RRcppGSL/R/inline.R, we see that the
Windows side is currently empty:
if(.Platform$OS.type=="windows") {
LIB_GSL <- Sys.getenv("LIB_GSL")
gsl_cflags <- sprintf( "-I%s/include", LIB_GSL )
gsl_libs <- sprintf( "-L%s/lib -lgsl -lgslcblas", LIB_GSL )
know_flags <- TRUE
} else {
gsl_cflags <- ""
gsl_libs <- ""
know_flags <- FALSE
}
because there simply is not general way to set these for all Windows
systems. On Linux I have
edd@max:~$ gsl-config --cflags
-I/usr/include
edd@max:~$ gsl-config --libs
-L/usr/lib -lgsl -lgslcblas -lm
edd@max:~$
but on Windows all bets are, as usual, off as we can't even assume a sane
$PATH.
If you have fixes that work in a general setup, I'd be delighted to
incorporate them.
